Symposium 13: Current topics in reproductive physiology
Sperm competition and its function in evolution has been a topic of interest for some time, but recently there has been a small flurry of papers on the physiology of the reproductive tracts, especially the impact of male accessory gland secretions and sperm proteins on egg laying, fertilization, and even female behavior. With the publication of the Apis mellifera genome, more intricate physiological studies in honey bees and their relatives are becoming possible. Problems with Apis capensis in South Africa have spurred some interesting studies of worker reproduction. The intention of the symposium is to present some of the excellent detailed insights that are available from Drosophila, and to highlight some of the emerging work in social insects.
